The **CTX150-7-52LP-R** is a high-performance, low-profile power inductor/transformer manufactured by **Eaton (formerly Coiltronics)**. It belongs to the **OCTA-PAC® PLUS** series, which is specifically designed for high power density and versatility in DC-DC conversion. --- ### 1. Key Technical Specifications The electrical characteristics are defined by its dual-winding construction, allowing it to be used as a single inductor, a coupled inductor, or a 1:1 transformer. | Parameter | Specification | | :--- | :--- | | **Inductance (Parallel)** | 15.11 µH | | **Inductance (Series)** | 60.44 µH | | **Current Rating (Irms)** | ~2.56 A (Parallel) | | **DC Resistance (DCR)** | 0.0478 Ω (Parallel) | | **Operating Temperature** | -40°C to +125°C | | **Dimensions** | 11.43mm x 11.43mm x 6.35mm | | **Mounting Type** | Surface Mount (SMD) | --- ### 2. Core Features & Construction * **Dual Winding Design:** The part contains two identical windings. This allows engineers to connect them in: * **Series:** For higher inductance. * **Parallel:** For higher current capacity. * **Coupled:** As a 1:1 transformer for SEPIC or Flyback topologies. * **Material:** It utilizes a **Powered Iron** core material (indicated by the "-52" in the part number). This material offers low core losses at high frequencies and a stable saturation curve. * **Low Profile (LP):** The "LP" suffix indicates a reduced height profile, making it suitable for compact electronic assemblies where vertical space is limited. --- ### 3. Part Number Breakdown Understanding the nomenclature helps in identifying its specific properties: | Segment | Meaning | | :--- | :--- | | **CTX** | Series Identifier (Coiltronics) | | **150** | Inductance Code (15.0 µH nominal) | | **7** | Size/Power Rating | | **52** | Core Material (Material 52 - Iron Powder) | | **LP** | Low Profile physical package | | **R** | RoHS Compliant | --- ### 4. Typical Applications Due to its flexibility, the CTX150-7-52LP-R is commonly found in: 1. **SEPIC Converters:** Using the two windings to provide a non-inverted output that can be higher or lower than the input voltage. 2. **Buck/Boost Converters:** Standard voltage regulation in industrial electronics. 3. **Isolation:** Providing 1:1 isolation for signal or power paths. 4. **Battery Powered Systems:** Where efficiency and low DCR are critical. ---
